The invention discloses an electrical fire monitoring and early-warning method based on anintegration algorithm and a device, which comprises steps: S1 residual current of an electrical loop is detected; S2 the residual current is integrated for time to obtain a residual current integral parameter; S3 the voltage and the load current of the electrical loop are obtained; S4 electrical fire hidden trouble situations of the electrical loop are monitored and early-warmed according to integral parameters of various time periods; S5 the electrical fire hidden trouble situations of the electrical loop are alarmed and controlled according to the detection results of the residual current, the voltage and the load current; S6 the temperature on presupposed positions in the electrical loop is detected; and S7 an overtemperature integral parameter is obtained when the temperature is bigger than a setting threshold. The electrical fire monitoring and early-warning method based on the anintegration algorithm and the device are beneficial to check in hadden troubles in time in early stage by monitoring the residual current integral parameter, the redidual current, the voltage, the load current, the temperature and the overtemperature integral parameter and particularly monitoring the residual current integral parameter and the overtemperature integral parameter, and prevent the problem that electrical fire hidden troubles are not found in time.

The invention discloses a storage battery monitoring method and device, a vehicle and a computer storage medium. The storage battery monitoring method comprises the steps of acquiring the stage of the vehicle; acquiring corresponding vehicle condition information according to the stage of the vehicle; and sending corresponding storage battery state early warning according to the vehicle condition information and the storage battery alarm terms corresponding to the vehicle condition information. According to the storage battery monitoring method and device, the vehicle and the computer storage medium provided by the invention, the vehicle condition information corresponding to the stage of the vehicle is acquired, and the corresponding storage battery state early warning is sent according to the vehicle condition information and the storage battery alarm terms corresponding to the vehicle condition information, so that monitoring and early warning of the whole life cycle of the storage battery are realized, maintenance of the storage battery by a vehicle factory and a vehicle owner is facilitated, and the use experience of a user is improved.

The invention provides an active safety monitoring system and a monitoring method for a bridge erecting machine, belonging to the technical field of bridge erecting machine operation management. Including the stress detection unit, the stress detection unit detects the stress value on the main stress-bearing components of the bridge erecting machine, and transmits it to the controller unit for analysis, and the controller unit transmits the data to the data visualization unit, which uses BIM lightweight engine technology and The LED display screen loads the stress data into the 3D model for quantitative display of color blocks, realizes the monitoring, early warning and alarm of the whole process of bridge erecting machine construction, and facilitates on-site command and dispatch by managers; avoids insufficient monitoring and unskilled operation As a result, the equipment was overturned to ensure the quality of the project; it replaced the guardians set up in the previous operation process and reduced labor costs. The controller unit can control the actuator according to the analysis results, and then control the start, stop and reverse operation of the bridge erecting machine, so as to avoid safety risks and ensure construction safety.

The invention discloses a method and device for remote sensing monitoring of crop diseases and insect pests based on meteorological satellite data. The method includes: acquiring SMAP and TRMM satellite image data and preprocessing the data, selecting corresponding meteorological factors according to the types of diseases and insect pests, and using inverse distance weights The two kinds of satellite data are interpolated by the method to obtain the key meteorological element data with the specified spatial resolution and specified time resolution in the study area; the daily data of the key meteorological elements in the study area are calculated according to Beijing time; the corresponding pest and disease pests are established by mathematical statistics methods Incidence index meteorological evaluation model; According to the daily data of the key meteorological elements of the designated disease and insect pest types in the study area and the corresponding meteorological evaluation model of the disease and insect pest incidence index, the disease and insect pest incidence index is calculated in a period of ten days; Generate thematic maps. The present invention can improve the real-time performance and accuracy of early warning, and the monitoring range is wider.
